when you play 1000 of games it works out evenly for you as much as against you. So statistically the rankings for active players are not going to be effected so much by luck factors.
Yep, completely agree. This eliminates the ''tedious'' part of the game through time

I exagerated a bit when i said : ''way too much unbalanced''. It can for a game alone, but not from many of them.
